Iron fillings reveal a magnet's magnetic field. You can see a magnet's magnetic field by scattering tiny iron filings around it. The iron filings form a pattern that reveals the lines of the ...

How do you dust a star for prints? Scientists have the answer to this strange question: by reconstructing the magnetic field ...

Astronomers have finally unlocked a crucial piece of the planet formation puzzle by detecting the magnetic fingerprint of a ...

The magnetic field lines of a bar magnet can be viewed by using compasses or by shaking iron filings onto a platform above the magnet. Place the magnet on top of the paper in view of the document ...

The team found that the dust grains aligned with the magnetic field lines. This allowed the team to detect and measure the ...

This allowed the team to detect and measure the unseen magnetic field lines, much the same way iron filings can reveal the magnetic field around a magnet. The team thinks that the measured three ...

Description: A sealed glass tube filled with iron flings may be used to demonstrate magnetization of a ferromagnet. Shake the filings into the long thin section of the tube. Magnetize the filings by ...

From magnets on our refrigerators to powerful electromagnets used in medicine, its applications are vast and varied. Popular ...

The solenoids serve double duty — first, they move pieces of flat “fridge magnet” material close enough to attract iron filings. Their second duty is of course provide a clock tick that will ...
